What is an idler sprocket?

 

The idler sprocket gear refers to the gear that plays a transmission role between two transmission gears that do not contact each other, and meshes with these two gears at the same time to change the direction of rotation of the driven gear to make it the same as the driving gear. Its role is to change the steering and not change the transmission ratio, called the idler. Also known as intermediate wheel, intermediate wheel and bridge gear.

The main function of the idler is to change the steering of the driven wheel, increase the transmission distance, adjust the pressure angle, etc. The idler gear is a part of the gear train that plays a transitional role and will not change the transmission relationship. It is to make the force of the gear train more reasonable or to meet the layout of the entire transmission system. Its function is only to change the steering, but not to change the transmission ratio. The wheelbase can be extended through the idler gear. The number of its teeth has no effect on the value of the transmission ratio, but it will have an impact on the steering of the last wheel. It is a wheel that does not do work, has a certain energy storage function, and is helpful for system stability.

 

The idler is a wheel that does not do work, and has a certain energy storage effect, which is helpful for system stability. Idler gears are very common in machinery to help connect distant shafts. It just changes the steering and doesn't change the gear ratios.

 

The idler gear sprocket is a sprocket gear that is sandwiched between two gears and meshes with both gears. Its function is only to change the relationship between the rotation direction of the two gears before and after it, without changing the transmission ratio and cannot change the position.

 

The tensioning wheel appears in the belt drive or chain drive. Its function is to tension the belt or chain, reduce the vibration and energy loss during their movement, and change the position.

The guide wheel, as the name suggests, mainly plays a guiding role. In the design of the wheel train, in order to meet the design requirements and external dimension requirements, the direction of the belt is relatively complicated, but to ensure the wrap angle design of the idler pulley and the pulley, it is necessary The guide wheel is fulfilling the design requirements and the design wrap angle
